Contents

Libero IDE is used to program the Microchip FPGAs.

Work environment

At HEI, we laucnch Libero IDE directly from HDL Designer.

Files

The main design files are located in $PATH/Board/concat:

$DESIGN.vhd
$DESIGN.pdc

The Physical Design Constraints .pdc file specifies the I/O locations and electric levels.

Further design files are found in $PATH/Board/Libero:

$DESIGN.prjx
synthesis/$DESIGN_syn.prj
designer/impl1/$DESIGN.adb
designer/impl1/$DESIGN.ide_des
designer/impl1/$DESIGN.pdb

This second set of files is copied into a temporary directory which will be additionally populated by the numerous design files generated by the deign tool.

Tasks

Launching the tools is done in two steps.

  • with the top-level block selected, the prepare for synthesis task does the following:
    • the design tool generates a single VHDL file
    • the trimLibs.pl script replaces all library definitions with the one of work
  • the Libero Project Navigator task does the following:
    • the Update prjx.pl script updates the paths specified in the .prjx file to reflect the project location's.
    • the Libero IDE is launched
